As most of the weight of the material is carried by disc N, there is, until the reservoir is emptied, always a substantial amount of material in position to be scraped into openings M.

It will be apparent that whenever the handle is oscillated from its foremost to its rearmost position, or vice versa, disc Ill uncovers three openings I4 which are filled as they are uncovered, and simultaneously covers three previously filled openings l4. At the same time, diSc H closes the bottoms of the first mentioned three openings, so that they will retain the charge being delivered to them, and opens the three second mentioned openings, permitting their contents to drop through the funnel-like frame bottom into a receptacle which may be placed thereunder.

Hence, a given quantity by volume is discharged every time the handle is oscillated from front to rear position, or vice versa.

The embodiment of the invention above described is particularly suitable for kitchen use, as previously indicated, for coffee and similar ground or granular materials.

The device illustrated in Figures 3 and 4 resembles closely that of the first two figures, excepting that certain changes have been indicated in the anti-clogging device and in the reservoir.

The reservoir I08 is shown as of glass or similar material being formed in a cylinder having a closed end I09 adapted to be positioned at the top and having a thread Illia for securing it to the threaded flange I01 of the measuring and dispensing apparatus.

In this instance, the anti-clogging device is shown as made of a plurality of strips I23, set on edge and secured as by riveting, welding, brazing, or the like. This type of scraper is found to operate particularly well with powdered material, the particles of which are inclined to pack and stick together if given any substantial stationary base upon which to rest.

The parts of the dispensing mechanism can all be easily produced, as of sheet metal stampings, screw machine products, or molded fiber.

While I have described the illustrated embodiments of my invention in some particularity, obviously many others will readily occur to those skilled in this art, and I do not, therefore, limit myself to the precise details shown and described, but claim as my invention all embodiments, variations, and modifications thereof coming within the scope of the appended claims.

I claim:

1. A dispensing device comprising a reservoir, a movable bottom disc therefor adapted to support the weight of the contents of the reservoir, means for oscillating the disc, the disc being provided with an aperture, a stationary member below the disc having a material receiving space with which the aperture of the disc is adapted to be brought into alignment, and a second disc rotatable with the first disc, beneath the stationary member and having an aperture out of alignment with the aperture of the first disc, and adapted to be brought into alignment with the space of the stationary member, and a stationary scraper overlying the first mentioned disc.

2. A dispensing device comprising a reservoir, a movable bottom disc therefor adapted to support the weight of the contents of the reservoir, means for oscillating the disc, the disc being provided with an aperture, a stationary member below the disc having a material receiving space with which the aperture of the disc is adapted to be brought into alignment, and a second disc rotatable with the first disc, beneath the stationary member and having an aperture out of alignment with the aperture of the first disc, and adapted to be brought into alignment with the space of the stationary member, and a stationary scraper comprising a narrow upwardly extending bafile overlying the first mentioned disc.

3. A dispensing device comprising a reservoir, a movable bottom disc therefor adapted to support the weight of the contents of the reservoir, means for oscillating the disc, the disc being provided with a series of apertures, a stationary member below the disc having a plurality of material receiving spaces, there being twice as many spaces as apertures in the disc with which the apertures of the disc are adapted to be brought into alignment, and a second disc rotatable with the first disc, beneath the stationary member and having a series of apertures out of alignment with the series of apertures of the first disc, and adapted to be brought into alignment with the spaces of the stationary member, and a sta tionary scraper overlying the first mentioned disc and having a plurality of arms extending radially between said apertures.

4. A dispensing device comprising a reservoir, a movable bottom disc therefor adapted to support the weight of the contents of the reservoir, means for oscillating the disc, the disc being provided withan aperture, a stationary member below the disc having a material receiving space with which the aperture of the disc is adapted to be brought into alignment, and a second disc rotatable with the first disc, beneath the stationary member and having an aperture out of alignment with the aperture of the first disc, and adapted to be brought into alignment with the space of the stationary member, and a stationary scraper overlying the first mentioned disc, and a converging outlet beneath said measuring apparatus.
